Ceramides

Ceramides are naturally occurring lipid molecules that make up approximately 50% of the skin's outer layer. They form the 'mortar' in the skin's brick-and-mortar structure, filling the gaps between skin cells to create a cohesive, protective barrier. When ceramide levels decline — due to age, over-exfoliation, harsh cleansers, or environmental damage — the barrier becomes compromised, allowing moisture to escape and irritants to enter. Topical ceramides in skincare work by replenishing these depleted lipids, supporting barrier integrity and helping the skin function as it should. Multiple ceramide types (EOP, NP, AP) work together for the most complete barrier support.
